-HENRY C. GASKILL, OF MOUNT HOLLY, NEW JERSEY.

AGITATOR AND PARAFFlNE-EXTRACTOR FOR OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 236,490, dated January 11, 1881.

Application filed October 20, i880. (No model.)

To all whom it may concern.:

Be it known that I, HENRY G. GAsKILL, a citizen of the United States, residing at Mount Holly, in the county of Burlington and State of New Jersey, have invented a new and useful Improvement in Agitators and Pai-affine- Extractors for Oil-Vells, which improvement is fully set forth in thefollowin g specification and accompanying drawings, in which- Figure l is a side elevation of the agitator and extractor embodying my invention. Fig. 2 is a horizontal sectionjn line or ai, Fig. l. Fig. 3 is a vertical section, enlarged, in line y y, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to improvements in devices for agitating oil-wells and extracting paraftine therefrom, as will be hereinafter fully set forth. y

Referring to the drawings, A represents a cylinder, formed of metal or other suitable material, having its lower edge sharp, as at a.

B represents hails, formed of one or more pieces of metal, securely attached at theirlower ends to the upper end ofthe cylinder A.

C represents a disk or plate valve hinged to one of the hails B, and when in closed position resting on the top of the cylinder A.

The upper ends of the hails are rmly connected to a rod, D, of sufficient length for locating and operating the cylinder in the oilwell or tubing thereof, said rod being termed the sinker,77 and has attached to it a rope for raising` and lowering purposes.

When it is desired to extract the paraiiine gathered in the oil-well or tubing the cylinder is properly lowered into the tubing or bore of the Well, and when the edge c reaches the par affine it cuts down into the same, the quantity released striking the valve O from below and raising it. Asthe cylinder continues to descend the released parafine becomes above the valve, and when it is believed that a sufficient quantity of the parafne is released the cylinder A is raised. The mass of paraffine above the valve then presses on the latter and closes it, whereby said mass, resting on the closed valve, is brought to the surface. The mass is then removed, and, if desired, the cylcylinder A and produce iiush joints between them the lower ends of the hails are cut away or shouldered, and the contiguous portions of the inner face of the cylinder grooved to receive the cut-away portions ofthe hails, forming rabhet-joints, as at I). Rivets c are passed through the hails and cylinder, and properly headed, whereby the hails and cylinder are rigidly and reliably connected, and the inner and outer surfaces of the cylinder A are flush and unbroken at the places of connection with the hails. By this construction there are no projecting parts on the exterior of the cylinder to obstruct the working of the 'same in the bore or tubing, or on the interior of the cylinder to resist the stream, as it were, of the released parafline through the cylinder.

rlhe valve G is connected to one of the hails B by means of a pivot-pin, d, which is passed through ears c on the valve, near its circumference, and an opening in said bail B. The ears clap or embrace the bail on opposite sides, and serve to guide the valve in its motions, preventing lateral play and displacement ot' the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

lnA a device for removing parafne from oilwells, the combination, with the cutting-cylinder and its hails, 0t` a valve which is pivoted to one ot' said hails and provided with two lugs that st-raddle the hail, in order that they may he guided and braced thereby, substantially as set forth.
